Does ControlUp support multiple AD forests?

Yes, you can use ControlUp to manage multiple AD domains and forests, even if no trusts exist between them. In order to configure multiple AD forest support, simply click on the “AD Connections” button on the Settings ribbon. In this window you can add any domain, provided its name is resolvable using DNS and you have valid credentials. Most issues with connecting to foreign Active Directory domains and forests are DNS-related and can be solved by configuring DNS conditional forwarders from your primary DNS servers.
